Objectives.Tutoplast processed human cadaveric ossicular allografts are a safe alternative for ossicular reconstruction where there is insufficient material suitable for autograft ossiculoplasty. We present a series of 7 consecutive cases showing excellent air-bone gap closure following canal-wall-down mastoidectomy for cholesteatoma and reconstruction of the middle ear using Tutoplast processed malleus.Patients and Methods.Tympanoplasty with Tutoplast processed malleus was performed in seven patients to reconstruct the middle ear following canal-wall-down mastoidectomy in a tertiary ENT centre.Main Outcome Measures.Hearing improvement and recurrence-free period were assessed. Pre-and postoperative audiograms were performed.Results.The average pre operative hearing loss was 50 ± 13 dB, with an air-bone gap of 33 ± 7 dB. Post operative audiograms at 25 months demonstrated hearing thresholds of 29 ± 10 dB, with an air-bone gap of 14 ± 6 dB. No prosthesis extrusion was observed, which compares favourably to other commercially available prostheses.Conclusions.Tutoplast processed allografts restore conductive hearing loss in patients undergoing mastoidectomy and provide an excellent alternative when there is insufficient material suitable for autograft ossiculoplasty.

Prospective Longitudinal

To evaluate the hearing outcome in canal wall down mastoidectomy with middle ear reconstruction, prospective longitudinal study was done at National Institute of ENT, Dhaka from March 2015 to September 2016. Total 22 patients were included in the study undergoing canal wall down mastoidectomy with 6 months postoperative followup. Hearing outcomes were observed and compared with the preoperative hearing tests. Among the 22 patients 9 (39.1% of subjects) patients had hearing gain, 12 (52.2%) had hearing loss and 1 (4.3%) had no change in hearing postoperatively.Although disease clearance is the main objective in canal wall down mastoidectomy, hearing gain can be achieved if combined with ossiculoplasty and tympanoplasty. The hearing gain or loss depends upon the extension of disease and status of the ossicular chain. Most patients usually experience hearing loss more than the preoperative period due to removal of ossicle or ossicles for the sake of disease clearance.

<p class="abstract"><strong>Background:</strong> The aim of the present study was to determine hearing improvement in different types of tympanoplasties by comparing mean preoperative air bone (AB) gap with mean postoperative AB gap.

ABSTRACT Objective Cephalometric assessment of Eustachian tube (ET) parameters and audiological evaluation in Down syndrome (DS) and Chronic Otitis Media (COM) and comparison with controls. The ET length, Total Cranial Base (TCB), Posterior Upper Facial Height (PUFH), Maxillary Depth (MD), s-ba (sella-basion) to Palatal Line (PL) and s-ba to ET length were considered. Materials and methods The study comprised of 75 subjects of both sexes in the age range of 7 to 20 years. Digital lateral cephalometry was performed for DS, COM and controls (n = 25). Pure tone audiometry (PTA) and immittance audiometry (IA) was performed to assess audiological status. Results ET length, PUFH, TCB and MD was found to be significantly reduced in DS and COM. s-ba to PL and s-ba to ET was significantly reduced in DS and COM. The s-ba to PL and s-ba to ET length angle in moderate and severe CHL (Conductive Hearing Loss) was decreased significantly. The s-ba to ET length was significantly decreased in patients with B and C tympanogram. Conclusion Aberration in the dimension of the region of the ET can be considered as a predisposing factor for otitis media and conductive hearing loss in DS.

We describe two patients with stapes fixation, in both of whom Rosen mobilization seemed to be the most prudent surgical choice. In both cases, a useful hearing gain was achieved initially. In the patient with otosclerosis, the conductive hearing loss recurred and a stapedectomy was subsequently carried out. In the patient with congenital stapes fixation, the hearing gain was maintained for two years eight months. We believe that this technique still has a place in stapes surgery in rare instances.

Objectives To assess the feasibility of radiologic measurements and find out whether hearing outcome could be predicted based on computer tomography (CT) scan evaluation in patients with temporal bone fractures and suspected ossicular joint dislocation. Methods We assessed 4002 temporal bone CT scans and identified 34 patients with reported ossicular joint dislocation due to trauma. We excluded those with no proven traumatic ossicular dislocation in CT scan and patients with bilateral temporal bone fractures. We measured four parameters such as malleus-incus axis distance, malleus-incus angle at midpoints, malleus- incus axis angle and ossicular joint space. The contralateral healthy side served as its own control. Hearing outcome 1–3 months after the index visit was analyzed. We assessed diagnostic accuracy and performed a logistic regression using radiologic measurement parameters for outcome prediction of conductive hearing loss (defined as >20dB air-bone gap). Results We found excellent inter-rater agreement on the measurement of axis deviation between incus and malleus in CT scans (interclass correlation coefficient 0.81). The larger the deviation of incus and malleus axis, the higher probability of poor hearing outcome (odds ratio (OR) 2.67 per 0.1mm, p = .006). A cut-off value for the axis deviation of 0.25mm showed a sensitivity of 0.778 and a specificity of 0.94 (p < .001) for discrimination between poor and good hearing outcome in terms of conductive hearing loss. Conclusion Adequate assessment of high resolution CT scans of temporal bone in which ossicular chain dislocation had occurred after trauma was feasible. Axis deviations of the incus and the malleus were strongly predictive for poor hearing outcome in terms of air conduction 1–3 months after trauma. We propose a 3-level classification system for hearing outcome prediction based on radiologic measures.

Background: Orofacial cleft is one of the most common congenital malformations of craniofacial region. Otitis media with effusion causing conductive hearing loss is a considerable challenge for many children with cleft lip and palate. The aim of this study was to evaluate the prevalence of hearing disorders and associated malformations in these patients. Methods: The research population consisted of patients with cleft palate, between years 2012 and 2014, who were referred to Children’s Medical Center and Vali-e-Asr hospital in Tehran, Iran. Otoscopic examination, tympanometry, pure tone audiometry and echocardiography were performed for each patient. Results: Among patients with cleft palate, 73% suffered from hearing disorders. There was no relationship between prevalence of hearing loss and sex, presence of other congenital anomalies and degree of cleft, but middle ear diseases were significantly higher in children younger than 2 years. Among patients with cleft lip or palate, 10% suffered from cleft lip, 63% suffered from cleft palate and 27% suffered from cleft lip and palate. There was at least one congenital anomaly in 53% of patients. Conclusion: This study demonstrates high prevalence of otitis media with effusion and conductive hearing loss in patients with cleft. However, audiologic problems are alleviated when patients become older.

Dynamic assessment of hearing in pediatric patients having chronic suppurative otitis media with cholesteotoma was conducted. The patients included into the study were assessed after surgeries performed by canal wall up or canal wall down technique without any timpanoplasty. Functional outcomes and frequency of recurrence were estimated. We carried out a retrospective and prospective analysis of hearing ability in 35 children who had undergone surgery in ENT clinic of Saint-Petersburg State Pediatric Medical University (37 ears were operated on as two patients had bilateral lesions). Hearing ability was investigated by tone threshold audiometry. All the patients studied were followed up for not less then 1 year. Hearing ability was evaluated before the surgery,6 months and 12 months after the surgery. Hearing findings before the surgery in children operated on by canal wall up technique showed a more significant hearing loss than the ones done by the other technique. All ears demonstrated no significant hearing loss progress in both groups. However, the children after canal wall up surgery showed more frequent cholesteatoma recurrences which resulted in the need of other surgeries. Carrying out canal wall up surgery on the middle ear in children makes it possible to maintain hearing at a socially adequate level.
